Questions on how to use LTC1666's I to V convertor OP-AMP

Change the 200ohms resistors to 500ohms. 10mA*500ohms = 5V

Change the 200ohms resistors to 500ohms. 10mA*500ohms = 5V

In your answer, does 200 ohms mean only RFB resistance?
Or is it 200ohm from U1(LT1812) to GND?
Or is it both resistance?

please answer about my question.

Also, can the LT1812 OPAMP power supply connect +5V to V+ and GND to V-?

Waiting for your reply.

Thank you.

Both resistors need to be changed.  The LT1812 can run on a single supply, but the LTC1668 cannot.

We will send you additional questions for cross check.

LT1812 OPAMP power supply is +5V to V+ and GND to V- as single power

However, do you mean that the LTC1666/7/8 should be powered by VDD +5V and VSS-5V dual power?

please answer about my question.

Right, the LTC1668 needs a split supply.
